Cops release photos in assault in doctor's office

Chicago police have released photographs of a man suspected of demanding money from a female doctor and attempting to sexually assault her in her North Side office Monday evening.

The doctor managed to disarm her knife-wielding assailant and badly cut him on one or both of his hands, police said this morning.

The doctor was alone in her office in a medical professional building in the 2900 block of North Commonwealth Ave. near St. Joseph Hospital in the Lakeview East neighborhood about 6:30 p.m. when a man came in asking for directions to another office, said Police Officer Laura Kubiak.

He then displayed a knife, put it to the doctor's throat and forced her to the floor, Kubiak said. The doctor, in her 30s, suffered a puncture wound to her thigh. She was also punched.

But "she managed to disarm him and cut him" before he fled, Kubiak said.

He was described as a black male, 20 to 30 years old, 5-foot-8 to 5-foot-10, 145 to 160 pounds, with dark skin and dark hair. He wore a plaid shirt and blue jeans and carried a dark-colored single strap back pack.
